That would be nice if the 130W, 100amp limits only applied to turbo mode. That is not what the toms article says, but they could be wrong. All those i940's reaching 4ghz at idle is not relevant, as no chip will reach 130W at idle. The claim by tom's is once the chip is loaded (prime etc) if load exceeds those limits the "cpu reduces its clock speed" . What I would like to see is several of those i940's at load with prime or linpack with cpuz showing the clock speed to make sure it does not downclock on load.
